BURNER FOR OIL-VAPOR STOVES.

SPECIFICATION forming part of Letters Patent No. 584,569, dated June 15,1897. Application filed December 12, 1896, Serial No. 615,472. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE WASHINGTON, of Brussels, Kingdom of Belgium,have invented certain new and useful Improvements in Burners forOil-Vapor Stoves; and I do hereby declare the following to be full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in burners for vapor-stoves, theobject being to provide a burner designed for burning a mixture ofpetroleum-vapor and air that will combine simplicity and economy inconstruction with durability and efficiency in use.

A further object is to provide a burner for burning petroleum-vapor witha vaporizer removably secured in place; whereby it can be readily andquickly removed from the burner.

With these ends in view my invention consists in the parts andcombinations of parts, as will be more fully described, and pointed outin the claims.

In the acconilpanying drawings, Figure 1 is a view in perspective of astove embodying my invention. Fig. 2 is a View in vertical section,takenlongitudinally through the mixing-chamber. Fig. 3 is a view in verticalsection at right angles to Fig. 2, and Fig. 4 is a view of thevaporizing-tube.

The burners herein described are adapted for use 011 any of the variouskinds of oilstoves now in common use; but for the pur- 5 pose ofconvenience I have described myimprovement in connection with a simpleform of single-burner stove.

The stove shown consists simply of two rings a a, separated and securedin proper position relatively to each other by the inwardly-curved armsB. The lower ring a constitutes the base of the stove, While the upperring a constitutes a rest for a pan, kettle, or other article.

The arms 13 are provided on their inner faces with the shoulders I),whichlatter form a rest for the burner O. This burner consists of a tube0, bent into circular form and permanently secured at its ends to themixing-chamber D. This chamber D is cylindrical in form and communicateswit-h the circular burner-tube 0 near one end, the main portion of themixing-chamber being in a plane outside of the periphery of the circularburner C. 5

Depending from the inner end of the mixing-chamber is the air-tube E.This tube is L-shaped, the depending or vertical member thereof havingits lower end open for the free entrance of the air, while thehorizontal memher thereof projects within the chamber I) and terminatesnear the outer end of the lat ter. Secured to the circular tube 0, at apoint diametrically opposite the mixingchamber, are the straight tubesF. These 6 5 tubes communicate with the circular burner O, extendparallel horizontally toward the inixingchamber, and terminate adjacentto the inner end of said mixing-chamber. The circular burner G and tubesF are provided on their upper faces with narrow slits or gas or vaporescape apertures of any desired shape and size, and hence it will beseen that any gas or vapor discharged into the mixing chamber will bemixed with air and escape into the circular burner and from the latterto the straight tubes.

My stove is designed, primarily, for burninga mixture of petroleum-vaporand air, the petroleum being stored in a reservoir remote So from thestove and fed thereto through a small tube. This tube (not shown) iscoupled up at (Z to the stuffing-box G, which latter is removablysecured to the vaporizing-tube II. This tube H is straight throughoutits length and is provided at its discharge end with the removablenipple 6, having the conical bore e, through which the needle-valve Lpasses. This needle-valve passes through the tube II and through thestuffing-box G and is secured at its outer end to the sleeve J, whichlatter is mounted on the stuffing-box. While I can secure theneedle-valve to the sleeve in various ways, I prefer to secure it by thelever J the inner end of which bears against 5 the valve and looks it tothe sleeve. The sleeve is provided with a spiral slot j, open at thetop, which slot is designed to receive the lug j on the stuffing-box G.From thisitwill be seen that by pressing on lever J in a direction torotate the sleeve the latter is rotated and by means of the spiral slottherein is also moved longitudinally, thus moving the needle-valvelongitudinally and opening or closing more or less the discharge-orificein the end of the vaporizing-tube H. This tube is removably secured in aposition between and in a slightly higher plane than the straight tubesF, so that the flames from the combined air and vapor burned in thestraight tubes keep the vaporizing-tube sufficiently heated to vaporizethe oil therein. The discharge end of the tube passes through an openingin the air-tube E in line with thehorizontal portion thereof, and hencethe vapor generated in the vaporizing-tube is discharged into theair-tube and, creating a suction therein, draws up air through thevertical portion of the tube E. The air and vapor thus brought togetherin the air-tube are discharged against the closed end of the air-mixerand deflected thereby, thus causing a thorough commingling of the airand vapor. This mixed air and vapor then passes into the circularburner, and part of it enters the straight tubes and is burned as itissues from the escape-orifices.

The vaporizing-tube is supported at its discharge end by the air-tube Eand near its outer end by the bearing L, carryingthumbscrew Z, adaptedto bear against the tube and hold it in position. The bearing L isattached to and supported by the circular burner O, and the portion ofthe latter immediately under the tube is recessed for the reception ofthe tube, the concave face of the recessed portion being provided withorifices for the escape of the vapor immediately below at the sides ofthe tube, thus causing the end of the tube adjacent to the oil-supplypipe to be highly heated.

By locating the vaporizing-tube well down on theburner and by heating itthroughout its length all the oil entering the same is vaporized, and asthe mixing-chamber is also heated by its proximity to the burner alldanger of condensation is overcome, and by making the vaporizing-tubestraight and removably securing it in position it can be readilydetached and deposits of carbon, either external or internal, removed.

M is a cup designed to hold oil or alcohol, which when ignited heats thevaporizing-tube and starts the vaporization of the oil. After thevaporization of the oil commences the mixed air and vapor escaping fromthe orifices in the straight burner-tubes is ignited by the flame fromthe starting-cup and in turn ignites the vapor escaping from thecircular tube. This starting-cup is secured in place under thevaporizing-tube by the yoke M, secured to the cup and embracing theair-tube.

It is evident that numerous slight changes might be made in the generalform and arrangement of parts herein shown and described withoutdeparting from the spirit and scope of my invention, and hence I wouldhave it understood that I do not limit myself to the precise detailsherein shown and described; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
